Schumann Systems short movies of systems collecting data.

This is a short movie of the system designed to
plot Schumann signals in three ways. One method actually counts the
strikes with a lightning plotter program and then plots totals on a real time
blue world map. As the day goes by the Schumann signals are plotted on the
known chimney times for the three major lightning areas of the world. (see the
chart) The other method does the same chart but uses a Spectrum Lab designed ,
radio reception of the Cavity instead of lighting strikes that are plotted.
The other mode is controlling two Arduino beam generators that allows plotting
lightning on a map in real time. That is what most of the buttons and
knobs on the main program window are for. The viewer in the same program
allows viewing in real time as well as viewing recorded plots recalled on the
calendar. This short movie is of the system running in the Spectrum
Lab radio reception mode. 7.8 Hz of the Schumann Cavity.
